Trends in Physical Properties of Group 13 Elements

The video tutorial covers the properties and trends of Group 13 elements, including boron, aluminium, gallium, indium, and thallium. It discusses their electronic configurations, atomic and ionic radii, melting and boiling points, ionization enthalpy, electronegativity, metallic character, and density. The tutorial explains how these properties change down the group and compares them with Group 2 elements. Key points include the unusual crystal structures affecting melting points, the shielding effect influencing atomic radii, and the trends in ionization enthalpy and electronegativity.
